Modified postfix-to-mailman.py for recipient_delimiter="-", VERP questions
by Jens Benecke Aug. 7, 2005

Aug. 7, 2005

Hello, for people moving from Qmail to postfix it's common to have to set the "recipient_delimiter" to "-" because that's QMail's default. I have a thousand users relying on this setting and I wanted to use Mailman. For ease of setup I used the "mailman:" transport configuration for dedicated mailing list domains and the postfix-to-mailman.py script and saved myself the trouble of setting up aliases and virtual settings. However, due to Postfix's adress extensions the configuration line in … [View More]master.cf needs to be changed. I posted this in the SysCP forum at http://www.syscp.de/forum/viewtopic.php?p=12500, and here's a quick cut&paste copy: I have a few questions: - Did I open any new pitfalls with the below configuration? How about bounce detection and VERP? - Is postfix-to-mailman.py compatible with VERP at all? AFAIU, VERP appends a code to the return path so that it looks like "listname-bounces+114abc2934....(a)domain.com". The postfix-to-mailman.py script seems to pipe the mail to "/var/lib/mailman/mail/mailman bounces+114abc2934...", will this work? How do I find out more about how mailman processes bounces internally? - Does Mailman split the VERP extension automatically or does Postfix need to do this, assuming all mail to the mailinglist domains get fed to the "mailman:" transport anyway? ========================================================================== What do you get? - Mailman with multiple domains. - NO "real" virtual domains - list names must all be unique. "news@domain1" and "news@domain2" cannot coexist. - Dedicated domains for list. One domain (or subdomain) cannot contain both lists and real email adresses. A possible patch is here: http://sourceforge.net/tracker/index.php?func=detail&aid=943827&group_id=10… - No alias files maintenance. Just insert the domains you want to use for lists in the transport table (hash file or MySQL) and in Mailman's "mm_cfg.py", and add the lists via "newlist". - VERP does not work - I think - because it uses "-" *and* relies on "+" as the extension (recipient_delimiter). I think. Here goes: - Install Mailman. - Configure mailman according to the comments in "/etc/mailman/postfix-to-mailman.py" - optionally, replace the transport and relay-domains maps with mysql tables and create mysql tables accordingly (this allows for later SysCP integration): Code: recipient_delimiter="+" owner_request_special = no transport_maps = mysql:/etc/postfix/mysql-virtual-mailman-transport.cf relay_domains = mysql:/etc/postfix/mysql-virtual-mailman.cf mailman_destination_recipient_limit = 1 - If you use recipient_delimiter="-", you need a wrapper script for postfix-to-mailman.py which you must call in master.cf, which basically re-appends the -extension to the user name. Then, in master.cf you must call this wrapper script with ${nexthop} ${user} ${extension} as parameters. Alternatively, patch postfix-to-mailman.py to accept two *or* three parameters (but I don't know enough Python to do that). Code: #!/bin/bash test -z "$3" || DELIM=- cat | /etc/mailman/postfix-to-mailman.py "$1" "$2$DELIM$3" - Alternatively, if you use Postfix 2.2 (when released), skip the wrapper script and replace ${user} in the master.cf maildrop line with "${user}${extension?-}${extension}". ====================================================================== Comments welcome! -- Jens Benecke (jens at spamfreemail.de) http://www.hitchhikers.de - Europaweite kostenlose Mitfahrzentrale http://www.spamfreemail.de - 100% saubere Postfächer - garantiert! http://www.rb-hosting.de - PHP ab 9? - SSH ab 19? - günstiger Traffic [View Less]

Premature end of script headers
by Mark van Dijk Aug. 6, 2005

Aug. 6, 2005

Hello, I have created my own mailman installation on a system I do have root access on, but already hosts a mailman version and I wanted to run my own. The group and username I created both are 'vocisml'. The cgi are not suexeced so every script should be ran as www-data. I launched configure with these parameters: ./configure --prefix=/home/vocisml/install/mailman --with-groupname=vocisml --with-username=vocisml --with-cgi-gid=www-data After this I ran make and make install, ofcourse. … [View More]

Issues with domain name.
by Todd A. Harrington Aug. 6, 2005

Aug. 6, 2005

I have Mailman version 2.1.5p1 running on my VPS using cPanel. I had a user setup his lists on a test domain "testdomain.com" and then I thought I could manually move the lists over to his real domain "realdomain.com" once the DNS changes went through. This is where I messed up! :( I went to the "/usr/local/cpanel/3rdparty/mailman/lists" directory then did a "mv listname_testdomain.com/ listname_realdomain.com/" Now when I go to: http://realdomain.com/mailman/admin/listname_realdomain.com … [View More]

Mailman "host_name" security issue?
by Jens Benecke Aug. 6, 2005

Aug. 6, 2005

Hello, I haven't found this at Google so maybe nobody has thought about it yet. I use Postfix with postfix-to-mailman.py and no alias setup. I also use several domains. Some of them are in the mailman transport table and only used for mailing lists. (whatever(a)lists.domain.foo) If you have some domains used by lists, and some used for normal email, what happens if you have a mailinglist called abc(a)lists.domain.com an user account called abc(a)domain.com and the list … [View More]

Postfix recipient_delimiter="-" and Mailman
by Jens Benecke Aug. 6, 2005

Aug. 6, 2005

Hello, I have converted a QMail installation to Postfix and kept the recipient_delimiter as "-" because with QMail it was default and my users expect this. However, this seems to conflict with Mailman's addressing scheme. All list functions are working execpt those who need to send mail to list-owner / list-subscribe or unsubscribe etc. I suspect this would be because of the recipient_delimiter. Is there an (easy) way of changing the delimiter in Mailman? I am using the postfix-to-mailman.py … [View More]

Strange behaviour: posts not appearing
by llasher Aug. 5, 2005

Aug. 5, 2005

Hi, I am new to Mailman, and thought I had set it up properly. I have enabled a list using the Plesk cpanel of my webserver, subbed some people and posted once myself. This first post appeared but subsequent posts from two different (subbed) email addresses of mine have not. Replies to previous posts have appeared, but not my new posts. I am bewildered as to why my initial post (the first one to the list) has appeared but no others. I have used pretty much the default settings to Mailman. I … [View More]
